Working Principle of AS1340A-BTDM-10

The working principle of AS1340A-BTDM-10 is simple. It consists of a booster, a controller, and a MOSFET. When the input voltage (Vin ) exceeds the output voltage (Vout ), the device begins to boost or regulate the voltage. The controller controls the MOSFET to switch the current from the booster and the output voltage to the desired level.

At lower input voltages, the voltage is regulated by the controller, thus keeping the output voltage constant. When the voltage increases, the controller switches the MOSFET from OFF to ON, thus boosting the voltage and raising it above the input voltage. This feature is suitable for power delivery applications, where a higher output voltage is needed.

At the same time, the controller can also reduce the current consumption, to maintain the desired output voltage. This enables the device to save energy and reduce the overall power loss of the system. Additionally, it also features a thermal shutdown feature, which safeguards the device from thermal overload.

AS1340A-BTDM-10 is a cost-effective and reliable device, suitable for multiple applications, allowing users to select the desired output voltage through two separate power outputs. Additionally, its ultra-low dropout, current limitation, and transient protection features make it an ideal choice for various portable and battery-operated applications.
